摘要
随着人类认识的提升,改善河流生态环境已得到越来越多的关注,采用生态补水的方式对提高河流生态环境具有重要意义。在定性分析七浦塘沿线区域水环境问题的基础上,采用水量平衡法并结合换水率计算方法对研究区生态环境需水量进行了计算分析。计算结果表明:①沙溪镇段的生态环境需水量最大,其次为支塘镇段及巴城镇。②所得到的七浦塘沿线生态补水重点区域及各区域水量分配结果,可为水量生态调度提供依据;对于七浦塘沿线的生态环境需水问题,可采取生态调度方式辅助解决;对于重点区域的生态环境需水问题,可通过增加换水次数加以改善。
With the improvement of human cognitive ability, the improvement of river ecological environment has received more and more attention. Ecological replenishment is of great significance to improving river ecological environment. On the basis of qualitatively analyzing the water environment problems along the Qiputang River, the water balance method combining water exchange rate are used to calculate the ecological water demand. The results show that Shaxi Town has the largest water demand, followed by Zhitang Town and Bacheng Town. The determined key areas of ecological water replenishment along Qiputang River and ecological water demand of each region can provide a basis for ecological regulation. Ecological water demand along the Qiputang River can be partly satisfied by water ecological dispatch, and water environmental problems in the key areas can be improved by increasing the water exchange times.
